CLOSURE DEVICE FOR LIQUID CONTAINERS SUCH AS PAINT CANS 3 Sheets-Sheet 5 Filed July 25. 1962 OR. F IG. 8 w/c/mds g uaa/c A 7 ram 5K United States Patent 3,162,338 CLUSURE DEVHIE FUR LlQUlD CONTAKNIERS SUCH AS EAINT CANS Nicholas T. Grubelie, 680 Willis Ave., Williston Park, Long Island, N.Y. Filed .luly 25, 1962, Ser. No. 212,380 19 Claims. (Cl. 222-484) This invention relates to a closure device for liquid containers such as paint cans, and more particularly, to a device which may be mounted on the upper open end of a paint can and which will permit the contents of the can to be stirred and dispensed without removing the closure device from the can.

The plain fiat cover provided with the conventional paint can has several disadvantages. In order to dispense paint from the can the cover must first be completely removed by prying the cover oil? from the can body, an operation that is both bothersome and time-consuming, particularly if congealed paint has caused the cover to stick to the can body. This problem is obviated in the present invention which permits the paint to be dispensed from the can without removing the cover from the can body. That is, when the subject closure device is mounted on the can body in place of the original cover, paint may be dispensed from the can by merely pressing a lever which opens a discharge spout through which paint may be poured without the necessity of first removing the cover from the can body.

Another disadvantage of the conventional cover arrangement is that while the cover remains oil to permit access to the paint, the latter is exposed to the atmosphere thereby resulting in solvent evaporation, contamination and other deleterious efiects. These difliculties are practically eliminated by the present invention which prevents atmospheric exposure of the paint except for a small amount of air which is permitted to enter the can during dispensing of the paint so as to make up for the lost volume of dispensed paint.

A further object of the present invention is to provide in a closure device of the character described a mixing means for stirring the paint or other contents of the can without adversely affecting the protective functions noted above. More specifically, the subject closure device is provided with a novel sealing arrangement for the bearing of the rotatable stirring shaft so as to seal off the interior of the can from the atmosphere while permitting free rotation of the shaft to which the stirring impeller is attached.

Still another important object of the present invention is to provide a novel arrangement for removably securing the closure device to the can body by a simple manual operation and which will be economical in manufacture and convenient in use.

Although the subject to closure device may be frequently described herein as applied to a paint can, it is to be understood that the device is applicable to other types of fluid containers having upper open ends.

Other objects and advantages of the present invention will be apparent to those skilled in the art as the description proceeds or are inherent in the structure described belowj in connection with the accompanying drawings wherein:

FIG. 1 is a side elevational view showing the subject closure device mounted in assembled position on a can body with the lower portion of the latter being broken I on the line 33 of FIG. 2;

FIG. 4 is a partial top planview showing a modified form of securing means;

FIG. 5 is a vertical sectional view taken substantially on the line 55 of FIG. 4-;

F IG. 8 is a horizontal sectional view taken substantially on the line 88 of FIG. 1 and shows the manner of mounting the impeller blade to the shaft.

Referring first to FIG. 1, the reference numeral 11 indicates generally the subject closure device which is shown mounted in assembled relation on the upper open end of a conventional paint can body 12 in place of the usual fiat circular cover that comes with the paint can when purchased. As best seen in FIG. 3, the closure device 11 comprises a substantially horizontally disposed cover portion 13 of circular shape and slightly convex in cross sec tion.

Diametrically disposed on cover portion 13 at the periphery thereof are fixed a pair of securing means 14, 15, which maintain closure device 11 in assembled relation on the upper open end of can body 12. A pouring spout 16 is normally closed by a movable cap 17 which may be moved to an open position by manual operation of a lever 18. A mixing shaft 19 is rotatably and slidably mounted in a bearing 20 fixed to cover portion 13 (FIG. 3) and the bearing 20 is hermetically sealed by a sealing arrangement indicated generally at 21.

Referring again to FIG. 1, the paint can body 12 is conventional in construction and comprises a bottom wall 22, a vertical cylindrical wall 23 having an upper edge rolled into a bead or lip 24 (FIG. 3) extending peripherally around the upper edge of body 12 and formed integral with an inwardly extending annular flange portion 25 leading to a downwardly extending portion 26 cooperating with a horizontally extending portion 27 and an upwardly extending portion 28 to form the usual U-shaped channel extending around the upper open end of the can body 12. The peripheral edge of cover portion 13 is provided with a downwardly extending integral flange 29 which projects into the U-shaped channel and rests upon the horizontal wall portion 27 of the latter.

Pouring spent 16 comprises a pair of vertical sidewalls 31, 32 extending upwardly from a base 33 fixed to cover portion 13. Side walls 31, 32 are joined to an end wall 34 and another inclined end wall 35, all of these walls being joined: by a top wall 36 formed with a discharge orifice 37 communicating with the interior of the spout which in turn communicates with an opening 38 extending through cover portion 13.

Discharge orifice 37 of spout 16 is normally closed by cap 17. The latter is provided with an upstanding pin 39 Which projects upwardly through an elongated slot 50 formed in arm 41 of lever 18. The latter comprises a second arm 42 of channel-shape in cross-section and having a lower horizontal portion 43 and an upper horizontal portion 44 joined by an intermediate vertical web portion 45. Arm 41 is formed integral with the upper horizontal portion 44. Lever 18 is rotatably mounted on'a pivot pin 46 secured to cover portion 13. The outer end of lever 18 is provided with a curved portion 47 adapted to be manually gripped for operation of lever 13.

A spring 48 is coiled around pivot pin 46 and has an upwardly extending end portion 439 in engagement with arm 41 of lever 18 so as to bias the latter in a counter-' clockwise direction as viewed in FIG. 2, thereby moving cap 17 toward its closed position shown in said figure. Cap 17 is provided along opposite lateral edges with a pair of downwardly extending flanges 17a, 17b whereby cap 17 is guided for reciprocal slidingmovement along wise position.

Referring now to FIGS. 1 and 2, the two securing means 14, 15 for removably securing the subject device'- to the upper open end of a paint can are identical and web portion 58 and extending-upwardly therefrom jalong opposite edgesof the latter area pair of vertical portions 60, 61 each having an upper edge curving upwardly and outwardly as at 62 so as to form a. pair of. spaced vertito clamping .member 67 of the previously described modification, is provided with horizontally-spaced portions receiving therebetween the forward end of link member 104 pivotally connectedtosaid portionsby a pivot pin 110. It will be noted that pivot pm 110 is located at the intermediate portion of clamping member 7 At the forward or radially inward end of clamping member 109 is another pivot pin 111 which pivotally' connects said forward end to the radially inward portion of a locking element indicated generally by the reference numeral 112.

Locking element 112 is of U-shape in crosssection and comprises an intermediate web portion 113 which extends vertically at 113a and horizontally at '113b.

' Formed integral with web'portion 113 are flange portions coverportion 13 by screws 59. Formed integralywith cally extending'ears 63, 64 having aligned vertical slots 65 extending therethrough for receiving the oppositeends of a horizontally extending pivot 'pin 66. Y

As noted above, the mixing means comprises a vertical shaft 19 rotatably and vertically slidably mounted within bearing 20 fixed at the center of cover portion 13. Bearing 20 is provided at its lower end with a downwardly extending cylindrical portion 130 partially projecting into a cylindrical sleeve 131 having an integral horizontal portion 132 formed with an opening 133 through which extends the shaft 19. Sleeve 131 is filled with packing material 134 which is pressed against the lower horizontal surface 135 of cylindrical portion 130 by a compression spring 136 surrounding shaft 19.

The lower end of spring 136 abuts against a collar 137 fixed to shaft 19 by a set screw 138. The upper end of spring 136 abuts against the horizontal portion 132 of sleeve 131 so as to urge the latter upwardly toward bearing 20. This forces the packing material 134 into tight engagement with the lower surface 135 so as to effect a hermetic seal of bearing 20 while permitting shaft 19 to rotate and slide vertically therein.

The upper end of shaft 19 is provided with a conventional clutch element 140 secured thereto by a set screw 141 and adapted to be drivingly engaged by a conventional power tool (not shown) so as to rotate shaft 19 and thereby mix the paint or other fluid contents of the can. For this purpose, there is provided at the lower end of shaft 19 a horizontally disposed stirring blade 142 comprising, as shown in FIGS. 1, 6 and 8, a horizontally extending strip 144 of felt or similar material sandwiched between a pair of metal strips 145, 146. The sandwich is maintained in assembled relation by screws 147 extending through strips 144, 145, 146 and having nuts 148 secured to said screws. Stirring blade 142 is secured to the lower end of shaft 19in the following manner. As shown in FIG. 8. metal strip 146 bulges outwardly at 149 at its central portion so as to receive the lower end of shaft 19 which extends between the bulging portion 149 and the oppositely bulging portion 1500f the intermediate felt strip 144. A pair of screws 151 extend through suitable openings provided in metal strip 146 and are in threaded engagement with shaft 19 so as to maintain blade 142 securely attached to shaft 19. v

Secured to the intermediate portion of shaft 19 by a pair of screws 152 is an angularly-inclined stirring blade indicated generally at 153 and comprising a single strip of metal having its lower end secured to the horizontal metal strip 145 of stirring blade 142 by means of a rivet 154.

It will be seen that the lower horizontal edge of felt strip 144 rests upon the bottom wall 22 of can body 12. The bottomwall 22 engages felt strip 144 so as to urge shaft 19 upwardly against the biasing action of spring 136.

This enables spring 136 to urge sleeve 131 upwardly toward bearing 2% and thereby maintains packing material 134 in tight sealing engagement with the bottom surface 135 of bearing 20 when the closure device 11 is in assembled relation on can body 12. Thus slight variations in the height of can body 12 due to manufacturing tolerances are taken up by spring 136. The upper portion of bearing 20 may be externally threaded for attachment to a conventional power tool for drivingly rotating shaft 19.

Arm 42 of lever 18 is provided with a concave recess 42a adapted to engagingly receive the radially innermost surfaces of elements 70, 82 of securing means 15, when I lever"18 is displaced in a clockwise direction, so as to limit the angular displacement of lever 18 in said direction. It will thus be seen that either securing means or securing means 100 serves as a second abutment means which, cooperating with the first abutment means 52,

limits the swinging movement of lever 18 to predetermined extreme positions wherein cap 17 will be located in open and closed positions respectively. I

invention is adapted to dispense either a drop of paint or a whole gallon in less than a minute and to maintain the paint in condition for immediate use so as to avoid waste of material and time.

It is to be understood that the specific embodiments of the invention shown in the drawings and described hereinabove are merely illustrative of several of the many forms which the invention may take in practice without departing from the scope of the invention as delineated in the appended claims, and that the claims are to be construed as broadly as permitted by the prior art.
